BUTTON-HOLE-CUTTING ATTACHMENT FOR BUTTON-HOLE-STITCHING MACHINES.

SPECIFICATION forming part of Letters Patent No. 301,974, dated July 15,1884-.

Application filed October 24, 1883. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR FELBER, of Brooklyn, in the county of Kingsand State of New York, have invented a new and ImprovedButton-Hole-Outting Attachment for Button- Hole-Stitching Machines, ofwhich the following is a full, clear, and exact description.

This invention consists, principally, in applying a narrow blade to theneedle-bar of button-hole-stitching machines for cutting the button-holethrough the material in which the button-hole is to be made at the timeof stitching. the button-hole, said blade being arranged in line withthe needle and adapted to be held out of contact with the goods to beoperated on, except when making the edge-stitch in stitching the firstside of the button-hole.

The invention also consists informing the plate-button. with a recess orslot, in conjunc-' tion with which the blade acts in cutting; also, inproviding thespring-pressed stock to which the blade is attached with aside projection adapted to strike upon the right-hand upper clamp-armjaw that is, the jaw at the right hand in starting the button-holeforholding the blade out of'contact with the ma terial at the time theneedle is making the depth stitches in stitching the first'side of thebutton-hole; also, in providing the said right-hand clamp-arm jaw with alug or plate to act in conjunction with the said side projection on theknife-stock, and, also, the heel of the knife-stock, for holding theblade enti'rely out of contact with the material .in stitching thesecond or return side of the but ton-hole.

The invention also consists of the construction, arrangement, andcombination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan View of the cloth-plate, plate-button, slidingreversible plate, clamps, and cam-lever of a Union Button-Hole StitchingMachine, the plate-buttonand right-hand upper clamp-arm being formed inaccordance with my invention, the sliding plate being shown in positionto be reversed, and showing also a guide for placing the goods in themachine. Fig. 2 is a plan view of the same, showing the slidingplate inreversed position. Fig. 3 is a sectional elevation taken on the line orm of Fig. 1. Fig. 4 is a sectional elevation taken on the line y 3 ofFig. 2. Fig. 5 is a perspective view of the needle-bar having myinvention applied thereto. Fig. 6 is a rear elevation. of theknife-stock and knife removed from the needle-bar, and Fig. 7 is a 'planview of the plate-button.

, A represents the cloth-plate, B the reversible sliding plate, D D theupper clamp-arms.

to which the jaws E E are attached, and F F represent the lowerclamp-arms, all of which parts are of the ordinary construction, exceptthat the jaw E is provided upon its inner edge, and near its outer end,with the lug or small slotted plate a. The cam-lever F, for operatingthe clamp-arms D D, and the plate-button G are also of ordinary form,except that the plate-button has the small recess or slot 1) formed init' in front of the needle-orifice 1', into which slot or recess thecutting-blade d descends after passing through and cutting the materialin which the button-hole is being made.

H is the knife-stock, to which the blade cl is attached by the screw 0.The stock H is attached to the needle-bar I by screws g 9 passingthrough a slot, h, and is formed so as to hold .the blade (Z near to andexactly in front of the needle 6, and is formed also with the sideprojection, f, which stands to the right of the needle 6. The stock fitsloosely upon the screws 9, and the slot h is of such length as to permitthe stock to have a slight longitudinal movement, and the stock is heldpressed downward with considerable force by the spring J,

' attached to the needle-bar I above the stock.

K is a guide-plate attached to the sliding plate B by the thumb-nut 7c,and formed with the arm 70, which, when the guide is properly put inplace upon plate B, reaches under the upper clamp-arms, D D, as shown inFigs. 1 and 2, to assist the operator in placing the goods in themachine.

' In operation, the plate B will be brought to the position shown inFig. l, and the goods will then be placed under the jaws E E, with theedge thereof properly against the arm is of the guide K, and thenclamped by turning lever F in the ordinary way. The machine now beingput in motion, the needle-bar I will descend, causing the needle 0 topenetrate the goods either at the right of the elongated needle-orificei in the plate-button G, as shown in Fig. 4, forming the first depthstitch, or at the left of said orifice, as shown in Fig. 3, forming thefirst edge stitch of the buttonhole.

In forming the first and every subsequent depth stitch on the first side(the side first stitched) of the button-hole, the projection f willstrike upon the inner edge of the jaw E, as shown in Fig. 4, which willstop the further descent of the stockl-I, and thus hold the blade d outof contact with the goods.

In making the first and every subsequent edge stitch on the first sideof the button-hole,

the needle-bar I, being carried to the left from.

the depth stitch just made, will carry the stock 11 away from over thejaw E, so that the blade (I will descend and pass through the goods intothe recess or slot I) made in the plate-button G, making a narrow cleancut in the goods,

thus gradually cutting the button-hole at the same time and slightlyinadvance of the stitching. The machine having been run in this manneruntil the desired length of buttonhole has been reached, the plate Bwill be reversed in the ordinary manner to the position shown in Fig. 2,and the operation continued in the ordinary manner for stitching thesecond or return side of the button-hole. 13y reversing the plate B thesmall plate a, secured to the jaw E, will be carried to the oppositeside of the needle 0 and under the lower end or heel of the knife-stockH, as illustrated in Fig. 4, so that in making each edge stitch theplate a intercepts the full downward movement of the stock II, and thusholds the blade (I out of contact with the goods.

In making each depth stitch on the returnside of the button-hole, theknife (I will be held out of contact with the goods by the projection fstriking upon the edge of the jaw E, as illustrated in Fig. 4.

Although I have shown and described my invention applied to a 'UnionButton-Hole Stitching Machine, it will be understood that it may beapplied to other button-hole-stitching machines, and all or a portion ofit used with button hole attachments for ordinary sewing-machines andnot depart from the principle and spirit of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Thebutton-hole-cutting attachmentherein shown and described,consisting of a'sliding stock attached to the needle-bar and carrying anarrow blade in line with the needle, in combination with means,substantially as described, for holding the blade out of contact withthe goods at all times except when making theedge stitches in stitchingthe first side of the button-hole, as set forth.

2. The sliding spring-pressed knife-stock connected to the needle-barand carrying the blade, and having an apertured curved projection, incombination with the jaws or similar attachments, substantially as andfor the purpose set forth.

3. The sliding stock connected to the necdle-bar acted upon by a spring,and provided with a projection and with the knife having its edgearranged in line with the needle, in combination. with the jaw uponwhich said projection is adapted to strike, substantially as and for thepurpose set forth.

4. The combination, with the sliding knifestock H, attached to theneedle-bar and providcd with blade d and formed with projection f, ofthe jaw E, provided with the lug or small plate a, substantially as andfor the purposes set forth.

ARTHUR FELBER.
